I been reading quite a few links about trying to get 64bit userland running.. Seen xming's work getting gcc64 running.
My question is, apart from the increased amount of memory available to apps, what other advantages are there to run 64bit userland rather than 32bit? This it faster? After all, doesn't Solaris use 32bit userland too.

This also makes me think about the benefits of looking at an Athlon64 compared to a highend P4 as a future upgrade to my T-bird box (sorry for the non-sparc bit).

PS. I have an Ultra30 happly running standard Gentoo, but it's so-slow..

How do you do this?
My PCs are OCed, my Macs are OCed, my ti-86 is even OCed, and it's be too cool to OC my sun boxes!!
I have 4 sparc 5's and 2 Ultra 10's that aren't doing anything right now(well 1 sparc5 is installing Gentoo), and next week I'll have 2 1000E's to play with.

I must admit I haven't been brave enough to try this yet. But I googled around a bit and did find how to change the CPU speed via OBP. This example was to install a 440MHz CPU rather than overclock, but it gives you the idea.

Quote:

10. Install 440 MHz CPU with Solaris 2.6

If you run 440 MHz CPU on new installed system with Solaris 2.6, please follow the instruction below and please install patch #106125, #105181, 105604 on Solaris 2.6 version 3/98, install patch #105181 on Solaris 2.6 version 5/98. You can find these or the latest version patch at sunsolve.sun.com patch finder section.

Actions:
1. Get the system to the ok prompt by stop+a or control+break on PS/2 keyboard
2. key in these commands under ok prompt
ok setenv auto-boot? false
ok reset { system will reset then stop at ok prompt again}

ok also hidden
ok d# 404 at-speed
ok .speed { the speed should be 404 or lower MHz}
3. Install the OS 2.6. then the 2.6 patch files.
4. Verify your system speed under ok prompt
ok .speed { now it should display correct speed of CPU}
ok setenv auto-boot? true { set boot option to default }
5. Cycle power on the system to bring the CPU up to full speed

Having not played around with OBP before I'm scared that I might get an unbootable system and I don't know if you can set a jumper to reset the OBP to factory defaults like on a PC box. If you try it let me know how it goes._________________Asus A8V
